very plain bluntly triangular tubercle ; the sides of the clypeus are 

 striolate, and the head closely punctate ; the prothorax is excavated 

 in the same manner, but only the anterior part of the excavation is 

 striolate, the rest of the surface is foveate punctate, but the centre 

 of the lowest part of the excavation is smooth longitudinally ; 

 scutellum very sharply carinate in the centre and strigillate ; elytra 

 slightly broader at the base than the prothorax at its widest part, on 

 each side is a sharp dorsal carina the area intervening between that 

 costa and the slightly raised suture is sub-diagonally striate, the 

 wider one between the costa and the deflexed sides is deeply striate 

 quite longitudinally and the interspaces have each a series of very 

 remote, shallow punctures ; propygidium with a distinct longitudinal 

 median carina reaching short of the apex, and with the spiracle 

 conspicuously knobby ( $ ) ; the upper margin of the pygidium is 

 glabrous, broadly grooved in the median part, the outer edge is 

 reflexed and slightly sloping, and the surface appears to be depressed 

 on that account ; the sides of the abdomen are broadly reticulate 

 plicate, the pectus is striolate ; the ante-coxal process is transversely 

 dilated at apex and truncate ; the femora are sparsely punctate and 

 the tibiae greatly dilated in the middle and compressed. 



Length 11^ mm. ; width 5 mm. 



Hab. Natal ; no exact locality. 



Tkichoplus cordicollis, Waterh., 

 Ann. and Mag. Nat. Hist, (5), viii., 1881, p. 319. 

 Black, with the antennae and palpi piceous red ; shape of 

 T. schaumi, but with the elytra more parallel, the clypeus is very 

 sharply bi-carinate in the centre in the anterior part, but the 

 sculpture is the same, the anterior part of the head is not impressed, 

 and there is a distinct tubercle at the base ; the prothorax is 

 excavate in the centre but not so deeply and in a more quadrate 

 form, and the anterior part is very deeply impressed vertically on 

 each side, the dilated part is more angular near the lateral con- 

 striction, the excavation and also the sides are filled with foveate 

 punctures bearing each a short, fulvescent hair; scutellum striolate; 

 elytra with one dorsal carina, striolate in the same manner as the 

 two species alluded to, and with series of moderately remote, short, 

 fulvescent hairs ; propygidium simple, spiracle moderately sharp ; 

 pygidium vertical with the upper margin narrowly grooved, but 

 simple ; abdominal segments strongly striate reticulate ; pectus 

 striolate ; ante-coxal process broadly dilated at apex, truncate and 

 excavate there.
